Single-leg RDL (bodyweight pattern rehearsal)~200-400KB demo
Showing: Dumbbell Single Leg Deadlift — closest verified demo. Shows the Dumbbell Single Leg Deadlift performed with load. The primer's "bodyweight pattern rehearsal" is the identical hip-hinge pattern performed with empty hands, purely to groove the balance and hinge before the loaded Romanian Deadlift work later in the session.
Hinge at the hip over one leg, back leg reaches straight behind you for balance, 1-second pause at the bottom, then stand tall.
